I'm guilty of never measuring the pre-load for the kingpins when I had the swb. Always ran with no shims
But I got to thinking if I was to set the pre-load to specification as per the fsm, wouldn't it make a difference on a larger tyre such as a 33 considering the the stock tyre size is a 26? Much larger and heavier.
Again, most likely overthinking and over analysing.
